Compact Blower for Notebook CPUs

This Delta KDB0705HB blower is built for notebook and laptop CPU cooling where space is limited. It suits technicians replacing a failed original fan or integrators assembling thin-profile systems. Buyers needing a full heatsink assembly or a larger desktop tower cooler will not find that here.

Steady Airflow at Fixed Voltage

The unit runs on a 5 V supply drawing 0.4 A, delivering consistent blower-style airflow as long as power is present. Its four-wire, four-pin connection allows the host system to monitor and regulate speed under sustained thermal load. No onboard temperature curves or PWM profiles are stored on the fan itself.

Low Power Draw and Direct Exhaust

At 5 V and 0.4 A the motor consumes roughly 2 W, keeping power demand minimal for battery-constrained platforms. The blower housing directs air straight out of the chassis vent, avoiding internal recirculation. Acoustic character will depend on the laptop’s duct design and the speed curve set by the system firmware.
